Ideas for new Invasion maps in future map packs

Just wondering what you guys would want for more Invasion based maps. Comment on what you would like to see.

i personally think that playing on spire and boneyard have become boring and i can never play on breakpoint becuase people dont have the dlc so i was thinking this needs more variety hey wouldnt it be cool if we got some forge invasion maps to spice things up a little? give me your thought and maybe your invasion map too (my invasion map is Crevice (its in my file share if u want to see it))
